I'm trying to add universal rear wheels support to the Pigeon. I have succesfully added the same system to the stabilizer wheels before and all works fine, but there's an extremely weird issue with the rear wheels. Basically this happens: The generated Jbeam of the wheels is not what it's supposed to be, the shape is all wrong, no triangles, unknown materials, etc: Even weirder, if I equip one of the stabilizers, the Jbeam changes to the stabilizer Jbeam: And another thing, the car drives in reverse even though the powertrain debug shows that it's driving forward, so weird. Everything works fine on the stabilizer wheels but not on the rear ones, and the system is exactly the same: Nothing works and the console shows no errors. I am completely lost, I tried a solution from another thread to override the front spindle values in rear suspension part and re-override in rear spindles, but it doesn't work, it just makes me instantly exit the car on spawn and the Jbeam disappears (but the console still shows no errors). I have all the needed parts: wheel hubs with wheel slots, spindles, brakes, etc. I also tried overriding default Pigeon files but it changes nothing. Attaching my Jbeam files so you can test and see (custom wheels I added obviously won't work for you because I have them in other files). I have never experienced this problem before with any car.
